so when carrying my go kart around (which fits in the back with the trunk closed
) i got alot of dirt down in the crack between the trunk floor and the seatbacks (when in the "down" position) solution: two pieces of 4' long weather stripping. You can see the one piece on the top and the other is stapled to it below and bent in an O shape and pressed in between the seats. Works great, pops in and out in a snap and it stays in place.
